[ad_1] The Margin properties on the controls set themselves when dropped on the design surface. This feature may be needed if adjusting items on a Canvas but are mostly an annoyance when dealing with most Xaml control placement. Remove the Margin properties to see the controls in their correct location on the grid. [ad_2] solved … Read more
[ad_1] Coming top-to-bottom: Default constructor: List(); Copy constructor (where const & means it takes const lvalue reference): List( List const & ); Move constructor (where && means it takes non-const rvalue reference): List( List && ); [ad_2] solved what is the difference between these three constructors?
[ad_1] Interesting task. Try following code: List<string> list = Enumerable.Range(1, 6).Select(e => ((char)(‘A’ + e – 1)).ToString()).ToList(); List<string> temp = new List<string>(); int count = list.Count; int total = 1 << list.Count; for (int i = 0; i < total; i++) { int k = i; temp.Clear(); for (int j = 0; j < count; … Read more
[ad_1] Add a public overload which calls the recursive function with head: void reverse_print_list() {reverse_print_list(head);} The recursive function can now be made private. 1 [ad_2] solved How to pass the address of private data through main() function?
[ad_1] Take a look at this: SmtpClient.Send SmtpClient substitutes SmtpMail and works almost exactly the same. 1 [ad_2] solved How I can transform my C# code : System.Web.Mail” transform by “System.Net.Mail”
[ad_1] You should know the concept of pass by value and pass by reference, e.g: class A; f(A& x); using a ‘&’ sign to declare that here the parameter is using “itself”, not a copy. more, if you are just using a parameter without changing any value of it. using const before parameter type. e.g: … Read more
[ad_1] C++ doesn’t have reflection, and if something isn’t public in a class, you can’t get to it [within “non-tricks” C++ – and with tricks, it means using things like “knowing it’s 18 bytes into the structure, which will break as soon as you use a slightly different architecture, or someone alters the singleton, or … Read more
[ad_1] Please let me know if I missed something #include “stdafx.h” #include <iostream> using namespace std; void Print(int count, int countSub, int rolePerGroup, int userCount, int userPerGroup) { for(int roleCount = 1; roleCount<=rolePerGroup; roleCount ++) { if(userPerGroup == 0) { cout<<“Parent groups are: “<< count <<” | “<<“Sub group are : “<<countSub<<” | “<<“Role per … Read more
[ad_1] I’d say you’d probably be looking at setting up a proxy on your local network, pointing the machines you want parental control on to that proxy, and filtering the “allowed” traffic by either: Checking website address against a predefined blocklist, and/or Reading through the HTML looking for naughty words or phrases. How to create … Read more
[ad_1] I think you’re over complicating this. Just start at 0 and do powers of 10^((n-1)-i). Like so… int n = 4; // the number of elements in the arr. int sum = 0; for(int i = 0; i < n; i++) sum += (arr[i] * pow(10, (n-1)-i)); // here (n-1) = 3 std::cout << … Read more
[ad_1] Converting an object to a string will always implicitly call the ToString method, you cannot choose a different method. Implement your ToString method to return “true” or “false”: class YourClass { public override string ToString() { return “true”; // or return “false”; depending on your needs. } } You can call another method explicitly … Read more
[ad_1] Not only are you confusing the order or parametres in strcpy (it’s destination, then source, so strcpy(xstring, animalsarray[j][0]); would have it’s parametres inverted), you’re confusing a char with a pointer-to-char. xstring is a char, and you’re trying to use it as a string. If you want to set all the elements of the array … Read more
[ad_1] You can use std::getline from the <string> header to read a line into a std::string. Put that in a loop to read lines until you encounter one that starts with the “specific word”, or reading failed. If line found, display that line. Sub-task: find out how to check whether a std::string starts with a … Read more
[ad_1] You need a method to add void add(int a[][maxCols], int b[][maxCols], int res[][maxCols]) { int row, col; for (row = 0; row < maxRows; row++) { for (col = 0; col < maxCols; col++) { res[row][col] = a[row][col] + b[row][col]; } } } and create 2 matrix in main, add them and show the … Read more
[ad_1] Maybe something like this: var result= ( from s in db.Stands join cp in db.ContractProducts on s.Id equals cp.StandId join p in db.Products on cp.ProductId equals p.Id where s.EventId == 1 group p by p.Description into g select new { Description=g.Key, TotalArea = g.Sum (x =>x.TotalArea) } ).ToList(); Where db is the linqdatacontext 1 … Read more
